Why am I getting this error with this code? 

 

Fatal error: Call to undefined function display_form()

 

$errors=array();
if(isset($_POST['submit']))
validate_input();
if(count($errors) !=0)
{
	display_form();	
}
else 
    {
	display_form();	
}
function validate_input()
{
	global $errors;
		if($_POST["fname"] == " ")
		{
			$errors['fname']="<span style=\"color:red;\">
			Please enter your first name </span>";
		}
}

Ok, I fixed  that problem, but now it won't display the form. 

 

<?php
session_start();

IF (isset($_SESSION['cart'])){
foreach ($_SESSION['cart'] as $key => $value){
echo "Product Number $key Quantity $value<br />";
}
}
require_once("functions.php");
DatabaseConnection(); 
?>
